BACKGROUND OF THE INVENTION

[0001] The invention described herein may be manufactured and used bythe U.S. Government for Governmental purposes without the payment of anyroyalty thereon.

[0002] 1. Field of the Invention

[0003] The present invention relates to a method for fabricating bodyheating and cooling garments.

[0004] 2. Description of Prior Art

[0005] Military personnel, astronauts and other persons operating inextreme temperature environments typically require a heating or coolinggarment. Typically, such garments are air and vapor permeable andcomprise synthetic tubing that carries cooling or heating fluid medium.The tubing is in close body contact so as to effect transfer of the heator cold to the wearer of the garment.

[0006] The heating or cooling garment can be configured into differentshapes and sizes. For example, many heating or cooling garments aretypically configured as vests. The garment utilizes tubing that isattached to a liner. Since pressures within the tubing can reach 100p.s.i. (pounds/square inch), the mating of the tubing to its substratemust be fluid pressure-insensitive. The liner is then attached to afabric which forms the outer portion of the garment. These garments arepreferably stretchable and flexible to conform to the shape of the bodyof the individual. Furthermore, these garments provide mobility for armsand legs, and retain the tubing close to the body for more efficienttransfer of heat or cold. The flexibility produces relatively lessdamage to the tubing during garment flexure and substantially reducesthe likelihood of punctures or tears to the garment. Moreover, there isa requirement that these garments be relatively lightweight and easy toclean.

[0007] One conventional method for fabricating these garments involvessewing the tubing to a substrate or liner which is sufficiently porousto allow internal vapors to escape as well as to provide for airpermeability. However, a significant problem with sewing the tubing isreferred to as “needle holing”. Needle holing requires that every inchof the tubing be sewn to the porous substrate. Such a techniquesignificantly increases the risk of puncturing the tubing during thesewing process. Furthermore, the threads themselves provide a majorirritant when the tubes are pressed into contact with the body.Additionally, the sewing method is slow and expensive. Automated sewingtechniques are not viable options due to the difficulty of achievingregistration of the tubing with predetermined patterns.

[0008] Another disadvantage of stitching or sewing arises when chemicalprotective clothing is being fabricated. In such a situation, stitchingthe tubing to any substrate results in needle holes that permit unwantedchemicals to move from one side of the garment to the other. Oneconventional technique used in an attempt to eliminate this problem withsewing or stitching is to fabricate the heating/cooling garments with abladder sealed at its edges wherein the cooling fluid is containedwithin the bladder. However, while bladder-type garments do in factconduct heat away from the body or conduct heat to the body, theresulting garment is non-breathable, non-stretchable and non-flexibledue to the two-coated fabrics which are joined together by heat.Furthermore, flexibility of the garment is impeded when a relativelylarge volume of liquid is captured in the garment. Additionally, onlyconduction can be used to remove heat since a bladder-type garment posesan impermeable barrier against natural perspiration. Therefore, thebladder-type cooling garment completely eliminates the possibility ofevaporative or convective cooling. A further disadvantage of thebladder-type garments is that the edges of the bladder deteriorate whensubjected to pressures higher than 30 psi.

[0009] There are other conventional methods for attach tubing to a lineror substrate. One such method involves brushing or rolling adhesivesonto liners to adhere the tubing to liners. However, all lining porosityis destroyed when the adhesive is massively applied across thesubstrate.

[0010] Another conventional technique is to use adhesive tape to securethe tubing to the liner. Specifically, the adhesive tape contacts theliner to either side of the tube along its length. This technique isexceedingly difficult to implement due to the fact that when the tubingis formed around small radius corners, the overlying strip of tape hasto be notched in order to follow the tubing around the corners.Furthermore, tape impedes the ability of the garment to stretch and alsodegrades garment permeability. Additionally, tape does not alwayssufficiently adhere the tubing to the liner.

[0011] What is needed is a new and improved method for making such aheating and cooling garment that solves the problems mentioned in theforegoing discussion that are associated with conventional methods andalso provides all the desirable characteristics such as flexibility andpermeability. Furthermore, such a new and improved method should resultin a relatively lower per-unit manufacturing cost of the garment.

DETAILED DESCRIPTION

[0026] Referring to FIG. 1, wearer 10 is wearing heating/cooling garmentor suit 12 of the present invention. Garment 12 includes heating orcooling tubing 14 dispersed throughout garment 12. Tubing 14 is suppliedwith heating or cooling fluids via an umbilical connection line 16 whichis connected to a heating/cooling unit 18. Garment 12 is extremelyflexible, durable, and both air and vapor permeable so as to permitcooling via not only the conduction of the tubing adjacent to thewearer's, but also by the escape of vapor from the body to ambient (i.e.cooling via convection).

[0027] Referring to FIG. 2, garment 12 further comprises fusible fabric20 in an open weave or open lattice structure which provides therequired air and vapor permeability. Such a fusible fabric is describedin commonly owned U.S. Pat. No. 5,320,164, the disclosure of which isincorporated herein by reference. Fabric 20 includes a number ofpatterned dots 22 that adhere to the intersections between the wovenstrands 24. Such a configuration is also described in the aforementionedU.S. Pat. No. 5,320,164. In another embodiment, fabric 20 is not woven.In one embodiment, fabric 20 is fabricated from high pile fleece.Referring to FIGS. 3 and 4, there is shown pattern board 30 inaccordance with the present invention. Pattern board 30 has top surface31 and an opposite side (not shown). Pattern board 30 can be fabricatedfrom a variety of materials. In one embodiment, pattern board 30 isfabricated from a phenolic heat-resistant plastic. Other suitablematerials can be used. Pattern board 30 comprises a plurality ofchannels 32. Each channel 32 has a bottom surface 34 and a plurality ofturn-about members 36 a-z that extend upward from bottom surface 34.

[0028] Referring to FIG. 4, channels 42, 44 and 46 are all sized forreceiving tubing (not shown) used to fabricate a heating or coolinggarment. It is to be understood that each channel 32 can be configuredto provide channels 42, 44 and 46 of varying sizes in order toaccommodate tubing of various diameters.

[0029] Referring to FIG. 5, turn-about members 36 allow serpentinetubing configurations of different sizes to be fabricated. The size ofthe tubing configuration depends upon the size of the garment. Tubing 50can be wrapped around turn-about member 36 c of each channel 32 for arelatively small garment, or around turn-about member 36 a for arelatively large garment. In one embodiment, tubing 50 is perforated toform an air vest.

[0030] Referring to FIG. 3, the channel portions 44 and 46 that sharethe same piece of tubing 50 comprise a channel circuit. Thus, referringto FIG. 3, pattern board 30 comprises six channel circuits 52, 54, 56,58, 60, and 62. Although FIG. 3, shows just six circuits, it is to beunderstood that pattern board 30 can be configured to have less than sixcircuits or more than six circuits. As shown in FIG. 3, pattern board 30is configured to have a generic serpentine channel design that can beused to make garments of varying sizes. It is to be understood that thechannel configuration of pattern board 30 is just one example and thatother configurations can be used. Furthermore, the channel configurationcan be modified to provide channel portions 44 a and 46 a.

[0031] Referring to FIG. 6, there is shown an alternate pattern board 70in accordance with the present invention. Pattern board 70 generallycomprises a substantially flat surface 72 and a specific serpentinechannel configuration 73 that has lower portion 74 and upper portion 76.Pattern board 70 is suitable for fabricating a heating/cooling vest.Upper portion 76 defines one circuit and corresponds to the upperportion of the vest that covers the upper torso, chest and lowershoulder area of a wearer. Lower portion 74 defines another circuit andcorresponds to the lower portion of the vest that covers the abdomen,lower torso portion, and the hip area of the wearer. Upper portion 76comprises channel 82. Channel 82 is sized for receiving a specific sizetubing (not shown). Channel 82 has portions 82 a and 82 b through whichthe tubing (not shown) can enter or exit pattern board 70. Similarly,lower portion 74 comprises channel 80. Channel 80 is sized to receive aspecific size tubing (not shown).

[0044] a) applying a heat-activated adhesive upon the exterior surfaceof the tubing;

[0045] b) placing tubing 92 into the selected channel portions (i.e.portions 44 and 46) of pattern board 30;

[0046] c) placing a first fabric layer upon tubing 92 and removing anywrinkles in the first fabric;

[0047] d) ironing the first fabric to activate the adhesive and form abi-component laminate assembly;

[0048] e) lifting the bi-component laminate assembly from the patternboard and place the bi-component laminate assembly on a flat surfacewith the tubing side facing up;

[0049] f) applying a second adhesive to tubing 92 and the first fabriclayer;

[0050] g) applying a second fabric over the tubing and first fabriclayer such that the second fabric contacts the adhesive to form atri-component structure;

[0051] h) placing the tri-component structure in a press and applyingheat and pressure to the tri-component structure so as to activate thesecond adhesive; and

[0052] i) removing the tri-component structure from the press andallowing the tri-component structure to cure.

[0053] In a preferred embodiment, the ironing step is accomplished witha conventional consumer-type iron. In a preferred embodiment, the steamsetting of the iron is not utilized. In one embodiment, the secondadhesive is a moisture-cure type adhesive that is sprayed on the tubingand first fabric. In a preferred embodiment, the second adhesive is ofthe type that does not penetrate through the surface of the first andsecond fabrics. In a preferred embodiment, the second adhesive drieswithout stickiness. In one embodiment, the application of heat andpressure is accomplished via a press as described in the foregoingdescription.

[0054] In another embodiment, the method of the present invention isdirected to making a garment for heating or cooling a wearer wherein thegarment contains no tubing but does contain a plurality of interiorchannels therein for receiving heating or cooling medium or wires, e.g.fiber optic cables. Such an embodiment comprises the following steps:

[0055] a) providing pattern board 200 having a first side 202, a secondside (not shown) and channel configuration 204 formed in the first side202 that defines a circuit. As shown in FIG. 9, channel configuration204 comprises serpentine channel 206. Channel 206 includes portions 206a and 206 b that provide for the formation of inlet or outlets in thefinished garment to allow the introduction of heating or fluid medium,wires, fiber optic cable, etc. The portions of first side 202 that arenot part of channel 206 are indicated by numeral 208 and, in oneembodiment, are substantially flat

[0056] b) disposing a first layer of flexible material over first sideof the pattern board;

[0057] c) disposing an adhesive film over the first layer of flexiblematerial;

[0060] f) curing the laminate garment structure.

[0061] In one embodiment, each of the layers of flexible materialcomprises coated aluminum foil. In another embodiment, each of thelayers of flexible material is a film-based fusible material. In afurther embodiment, each of the layers of flexible material is atextile-based fabric. In one embodiment, the application of heat andpressure is accomplished by using a press as described in the ensuingdescription. Once the basic laminate garment structure is fabricated byany of the methods described above, excess fabric is trimmed away. Oncea pair of laminate garment structures are fabricated, the garmentstructures and be secured together to form the front and a garment, i.e.vest, with a front side and a back side of the garment. In oneembodiment, shoulder straps are used to attach the upper portions of thegarment structures together, and additional straps are used to attachthe side portions of the garment structures together. However, any oneof a variety methods for attaching the garment structures together canbe used, e.g. snaps, hooks and fasteners, hook and loops, Velcro™, etc.thereby allowing one size of the complete garment to fit wearers of manysizes. In a preferred embodiment, the garment structures are attachedtogether so as to provide a close fit with the body of the wearer inorder to maximize the heating or cooling effect. In one embodiment, sidepockets are included on the complete garment. In such an embodiment, theside pocket is configured as a stretch pocket of lycra fabric with azipper closure. In one embodiment, the side pocket contains the tubingthat feeds heating or cooling medium to the tubing interior of thegarment or receives heating or cooling medium from the tubing interiorof the garment. As described in the foregoing description, the tubingserves as a conduit for a heating or cooling medium. A typical heatingmedium can be hot or warm water, or heated gas (i.e. neon, fluorescent,etc.). A typical cooling medium can be cool or cold water, or cold gasessuch as freon or other refrigerants. Such heating or cooling mediums canbe applied via pumps or vacuum sources, or any other devices that createpressure. The tubing can also be used as a conduit for receiving wiresor fiber optic cables.

[0062] The adhesives described above are chosen from group comprisingpolyamids, polyesters, polyethylenes, polyvinyl chlorides, polyvinylacetates and polyvinyl acetate copolymers.

[0063] Thus, the present invention obviates many of the problems of theprior art and provides a stretchable, flexible, air permeable, vaporpermeable, and durable heating and cooling garment with a relativelylower weight and per-unit manufacturing cost. Furthermore, the resultingheating and cooling garment can be laundered and dry-cleaned.

[0064] The heating and cooling garment made in accordance with thepresent invention also has many applications, including, but notlimited, to garments for protection against chemical or biologicalagents and extreme temperature conditions. Thus, such garments can beused for military, sports and industrial purposes. Furthermore, thelaminated garment structures as described in the foregoing descriptioncan be used in other articles of manufacture as well, such as sleepingbags, tents, blankets, etc. Additionally, the laminated garmentstructures as described in the foregoing description can be used forentirely different purposes such as melting snow or ice from a surface,e.g. sidewalk, driveway, etc., or keeping items warm or hot, e.g. food,drinks, etc.
